Specification of Letters Patent.

Patented Feb. 11, 1908.

Application filed May 13. 1907. Serial No. 373.396.

,revolved or rotated relative to suitable paddles received therein, saidpaddles being station'ary throughout a churning operation, and

the parts being assembled in a substantialv and desirable manner tofacilitate operation.

The invention embodies particularly, pe

culiar 'and novel structural features which will be more fully describedhereinafter and which will be iinally claimed.

For a full understanding of the invention and the merits thereof andalso to acquire a knowledge of the details `of construction of the meansfor effecting the result, reference is to be had to the followingdescription and j accompanying drawings, in which:

Figure 1 is a side elevation of a churn embodying the invention; Fig. 2is a vertical longitudinal sectional view bringing out clearly thearrangement of the several parts of the mechanism, and Fig. 3 is atopplan view, the cover of the churn being removed.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Speciiicallydescribing the invention, and

`referring to the drawing, the numeral 1 indicates a stand which may beof any suitable construction and which preferably comprises sup ortinglegs 2. `Attached substantially to t e top of the stand 1 are spacedpillow blocks 3 in which is journaled a horizontal shaft 4. A smallpinion 5 is secured to one end of the shaft 4 and is in mesh with a gear6 carried-by a shaft 7 journaled in any desired manner in the upper endportions of spaced supporting members 8 which project upwardly from oneend of the stand 1 from an end of the latter. A crank handle 9 isattached to one end of the shaft 7 and is operated in order to turn thegear 6 and the shaft 4, connected therewith. The end of the shaft 4 oposite that carrying the pinion 5 has a beve gear 10 attached theretoand said bevel pinion is in mesh with a similar pinion 11, horizontallyarranged and journaled upon a stem 12 which projects upwardly from thestand 1 near the gear 10. At the lower end of the stem 12 andsurrounding the same is a cup 13 in which are received a suitable numberof ball bearings, the lower hub portion of the gear 11 being received inthe. cup 13 and being in contact with the ball bearings designated 14located inside of the cup. In other words the gear 11 is supported onthe ball bearings 14 and rotates freely in mesh with the gear 10.

The body 15 of the churn consists ofa suitable receptacle, and is alsojournaled'for rotation upon the stem 12. Said churn body is providedwith a tubular extension 16 located centrally of the bottom thereof, thetubular portion of said extension being coincident with an opening atthe center of the churn body 15. The under side of the churn body 15 isformed with downwardly extending projections or lugs 17 at oppositesidesof the opening therein and said lugs enter depressions or recesses 18 inthe upper side of the gear element 11 and an interlocking connection isthus established between the gear element 11 and the churn body, where'-bywhen the gear 11 is rotated the churn body will revolve therewith. Theextension 16 ofthe churn body 15 terminates at its upper end in theplane of the upper end of the churn body so that the liquid which is tobe operated upon may fill the churn nearly to the top thereof. The stem12 projects some distance above the -extremity of the Vtubular extension16 and received on the projecting portion of the stem is a collar 19.

Said collar 19 is provided with opposite horizontal threaded openingsleading tol the vertical opening which receives the stem 12 and in saidthreaded openings are received the threaded members 20. The members 20have the inner ends thereof adapted to engage with the stem 12 in orderto positively attach the collar `19 thereto, and each of the members 2()is formed with an opening leading from its outer extremity and threadedso as to receive the threaded extremity of a lateral arm 21 projectingfrom the upperportion of a paddle 22; In other words the members 20 notonly attach the collar 19 to 4the stem v12 but they also constitute supvpaddles 22 may be vertically adjusted by vertical adjustment of thecollar 19. Eac of the members 20 is formed at its outer end with a hubto admit of ready application of a wrench or similar tool for adjustingthe member in the manner s ecified.

The suitable cover 23 1s provided for the receptacle of churn body 15and said cover receives the upper portion of the churn body when theparts are in operative positions. The cover 23 is formed with a centralopening through which the upper extremity of the stem 12 passes, saidcover being thereby centered.

It is contemplated that the various shaft and gear elements of the churnshaft be mounted in ball bearings, if desired, in order to facilitatethe free revolution of the parts, and increase the ease of operation ofthe machine.

The paddles 22, being constructed with an irregular or angular contour,have a peculiar function of breaking up ythe cream, and also tend toprevent the cream from riding up the wall of the churn body by reason ofcen trifugal force.

I-Iaving thus described the invention what is claimed as new is 1. Inchurn operating mechanism of the class described, and in combination, astand, a horizontal shaft j ournaled u on said stand, a pinion at oneend of the sha t, an operating gear in mesh with said pinion, a bevelpinion at the opposite end of said shaft, a vertical stem projectingupwardly from the stand adjacent to said bevel pinion, a cup located atthe lower end of said stem and surrounding the latter, ball bearingsreceived in said cup, a horizontal bevel pinion journaled upon the stemand having'its lower hub portion resting upon the ball bearingsaforesaid, a churn body having a centrally upwardly projecting tubularextension at its central portion and through which the stem abovementioned passes, whereby the churn body is supported for revolution onthe stem, the bottom of the churn body being formed with an o eningcoincident with the tubular area of t e extension aforesaid, lugsprojecting from the bottom of the churn body on opposite sides of theopening therein, the top of the horizontal bevel pinion aforesaid beingformed with recesses receiving the lugs and establishing a detachableinterlocking connection between the churn body and said pinion, a collarapplied to the upper end portion of the stem, paddles attached to saidcollar and about which the churn body is adapted to rotate, and a coverfor the upper end of the churn body.

2. In churn operating mechanism of the class described, and incombination, a stand, a horizontal shaft journaled u on said stand, apinion at one end of the sha t, an operating gear in mesh with saidpinion, a bevel pinion at the opposite end of said shaft, a verticalstem projecting upwardly from the stand adjacent to said bevel pinion, acup located at the lower end of said stem and surrounding the latter,ball bearings received in said cup, a horizontal bevel pinion journaledupon the stem and having its lower hub portion resting upon the ballbearings aforesaid, a churn body having a centrally ,upwardly projectingtubular extension at its central portion and through which the stemabove mentioned passes, whereby ythe churn body is supported forrevolution on the stem, the bottom of the churn body being formed withan opening coincident with the tubular area of the extension aforesaid,lugs projecting from the bottom of the churn body on opposite sides ofthe opening therein, the top of the horizontal bevel pinion aforesaidbeing formed with recesses receiving the lugs and establishing adetachable interlocking connection between the churn body and saidpinion, the upper end portion of the stem projecting some distance abovethe up er extremity of the tubular extension, a co ar disposed upon andreceiving the upper extremity of the stem, horizontally threaded membersscrewed into said collar and adapted to engage the stem to iix theposition of the collar thereon, said threaded members being providedwith internal threaded openings, paddles arranged in the churn body andhaving lateral arms at the upper ends thereof formed with threadedextremities received in the threaded openings of the threaded membersapplied to the collar, and a covervfor the churn body.

In testimony whereof I affix my signature in presence of two witnesses.Y ERIK A. COLLIN.
